VERMIVORA CELATA ORESTERA Oberholser ROCKY MOUNTAIN ORANGE-CROWNED WARBLER HABITS Although recognized and described by Dr. Harry C. Oberholser (1905) over 45 years ago, this well-marked subspecies was not accepted by the Committee for addition to the A. O. U. Check-List until comparatively recently. It is described as "similar to _Vermivora celata celata_, but larger and much more yellowish, both above and below." Dr. Oberholser (1905) adds the following remarks: "This new form has usually been included with _V. celata celata_, but breeding specimens recently obtained, principally from New Mexico and British Columbia, indicate its much closer relationship, in all respects except size, with the west coast forms. From _Vermivora celata lutescens_ it may, however, readily be distinguished by its duller, less yellowish color, both above and below, and by its much greater size." He gives its geographical range as: "Mountains of New Mexico, Arizona, and southeastern California to British Columbia; in migration to Minnesota and Pennsylvania, south to Texas, and Mexico to Lower California, Michoacán, Guerrero, and Puebla." _Nesting._--Stanley G. Jewett (1934) reports a nest within the range of this race, of which he writes:
